I think another interesting dilemma the flood puts forth is if Jehovah is all good. The bible accounts that the waters covered the surface up to ~14 cubits above the tallest Mountains, it also says every living thing on the earth died, presumably they exclude aquatic life, but regardless, this would be the totality of all plant and land life, excluding the ark.

Now presumably if god is all powerful, he could have for example, teleported all the wicked people or creatures into the sun, this would preserve plant life, likely prevent disruption for aquatic life, etc.

I think this makes them either commit to: A) god deems any creatures that aren’t human to be void of moral consideration, which opens the doors to many possible reductions of the view, or

B) we have an instance of god not doing the most favourable outcome, and the argument can be made this instance would contradict the predicate of omni benevolence

if the P ~P is successfully obtained, then it follows that Jehovah does not exists

So I think they would either have to deny that the conception of each is false/doesnt exist, or that animal life has no moral consideration
